My invention consists broadly in two cylinders and rotary cutters within the said cylin-H ders, and more particularly to mounting the cutters eccentrically within the cylinders whereby the cutters are brought into coaction at predetermined-times in the-'rotation of the cylinders.

The object of my present invention is to materially simplify the meansfor cutting and folding sheets fed froml a web, which means comprises rotary cutters mounted within the folding cylinders, the parts being so arranged that the operation of the folding devices and the rotary cutters will be proper y timed with respect to each other. V Furthermore, the parts are so arranged that the folding 0H of a predetermined number of sheets is accomplished which sheets arecombined and delivered to the desired point.

A practical embodiment of my invention is represented in the accompanying drawings in which Figure 1 represents in side elevation, the

. portion of a cutting and folding machine to lwhich my invention is directed, this view showing the geared connection between the drive shaft and the rotary cutters. Fig. 2 is a horizontal section on one-half the scale of Fig. 1, the section being taken throu h the rotary cutters and folding c linders. ig. 3 is a transverse section on t 1e same scale as Fig. 1, taken in the plane of the line A-A of Fig. 4 is a transverse section on the same scale as Fig. l, taken in the plane of the line B-B of Fifr. 2, looking in the direction vof the arrows. zFig. 5 is a transverse section on the same scale as Fig. 1, taken in the plane of the line (le-C of Fig. 2, looking in the direction of the arrows. Fig. 6 is a transverse section on the same scale as Fig. 1, taken in the plane ofthe line D-D of Fig. 2,looking in the direction of the arrows. FiO. 7 is a partial sec-tion in the same plane astFig. 6, showing the parts in another position, and Fig. 7 shows in detail the tail piece ot one of the sheet carriers and the cam for operating the same.

l The side frames of so much of a cutting and folding machine as will be necessary to give a clear understanding of my invention are denoted by 1 and 2. These side frames 1 and 2 are` rovided respectively with inwardly exten ed cylindrical lugs 3, 4 and 5, 6, through the lugs 3, 5 of which extends the rotary cutter shaft 7 eccentrically with respect thereto, and through the lugs 4, 6 of which the other rotary cutter shaft -8 extends eccentrically with respect thereto. Intermeshing gears 9, 1 0 for these shafts 7, 8, are provided exterior to the 'frame 1 and intermeshing gears 1 1, 12 are provided for the said shafts exterior to the frame 2. The cutter shaft 7 carries two cutter blades 13, 14, arranged diametrically opposite each other and the cutter shaft 8 is provided with two blades 15, 16 arranged diametrically opposite each other,l the blades 14, 15 and the blades 13, 16 of the two members being arranged to coact successively during the rotary movement of the cutters. These cutters are driven from the main drive vshaft 17 through a train of gears 18, 19, 20,10-

cated exterior to the side frame 1, the gear 20 meshing with the gear 9.

Two rotary folding cylinders 21, 22 are provided, the rotary cutter 7, 13, 14, being coated eccentrically within the cylinder 21 and the rotary cutter 8,15, 16, being located eccentrically within the cylinder 22. The folding cylinder 21 is provided at its ends with hollow hubs 23, 24, which are mounted to rotate on the cylindrical lugs 3, 5 and the cylinder 22 is sinnlarly provided with hollow hubs 25, 26, mounted to rotate on the cylindrical lugs 4, 6. These two cylinders are rotated at the same speed in opposite directions through interrneshin fixed to the hubs 23, 25, of t e two cylinders adjacent to the side frame -1. These cylinders are driven from the drive shaft 17 through a gear 29 located adjacent to the side frame 1, which Gear meshes with the' gear 27 fixed to the cylinder hub 23.

The cylinders 2l, 22 are provided with gears 27, 28,

IOO

three folding devices, in the present instance by providing cylinder 22 with three floating folding grippers 33, 34, 35, arranged to coact at predetermined times with their respective folding blades. These folding fdevices are` of the well known floating type, the box cam 36 for the cylinder 21 with three floating folding blades 30, 31, 32, and the,

. controlling the opening of the grippers` as -they are brought successively into posltion ing blades- 39,*31, 32, is mounted to vrotate .the sheets are folded off on to the cylinder 22.

'..'Three vslots 57, 5S, -59";are formed through cylinder 22.for permitting thelblades of the at the proper times during the rotary Inovements of' the cutters and .cylinders to sever s the sheets 'from the advancing web.

der. The boX cam 41 is rotated one revolution to every one and'on'e-third revolutions of the rotary cylinders so that a folding blade is arranged to coact with its gripper every one and one-third revolutions of the two cylinders for folding off a collected group of four sheets from the cylinderfZl on to the cylinder 22. This movement of the .rotary box cam 41 will also withdraw'the sheet carrier which engages theadvance edges of the group of -four collected sheets at the time they are folded off thecylinder 21.

The parts shown and described butnot claimed herein form the subjectfnatter of an application filed by me December 15, 1906, Serial No. 347,952, entitled cutting. and folding machines.` f

It is evident that various changes might be resorted to in theI construction, forniand arrangement of ,thev several part-s without departing from the spirit and scope of my invention. Hence Ido not wish to limitinyself strictly to the structure herein setforth,

butv What I claim is:

1. In a cutting andfolding machine, two

rotary cylinders andtwonco-acting rotary cutters both mounted to rotate within said cylinders.

y2. In a cutting and folding machine, two rotary cylinders rand two coacting.`rotary cutters both mounted to rotate eccentrically within `said cylinders.

3. In acutting and folding machine, two rotary cylinders, two ooacting rotary cutters both mounted torotate .within said cylinders and means for rotating the cutters at a predetermined speed with respect to the speedI of rotation of said, cylinders;

4. In a cutting and folding machine, two rotary cylinders, two coacting rotary cutters both mounted to rotate eccentrically within saidA cylinders and means for rotating the cutters at a predetermined speed with re-v pect to the speed of rotation of said cyliners.

5. In a cutting and folding machine, two rotary cylinders, rotary. cutters mounted within said cylinders and means vfor rotating the cutters one revolution `forevery twothirds of a revolution of said cylinders.

6. In a cutting andv folding machine, two rotary cylinders, rotary cutters mounted eccentrically within said cylinders and means for Hrotating the cutters one revolution for ver y two-thirds of a revolution of said cyliners.

In testimony', that I claim the foregoing as my invention, I have signed my name in presence of two Witnesses, this I'Sthvday of .RALPH SEYMOUR.
